Unknown USB Device(Device Descripter Request Failed)

Q:Unknown USB Device(Device Descripter Request Failed)

hello i'm an embedded developer. i have an usb type ic programmer to burn microcontroller. now i'm getting this error "Unknown USB Device(Device Descripter Request Failed)" while plug my usb programmer into my pc socket. but this same hardware support in my friend same hp430 pc.

I upgraded to Windows 10 a while back. Every time I open the computer I get a pop-up notification telling me the USB device is unrecognized. I have no USB devices in any of my 3 USB ports.
I sent my computer in twice. No help. They just uninstalled everything and reinstalled everything and told me it should be fixed. It is not. I then went about updating every driver in my Device Manager. I uninstalled the Unknown USB Device and then updated
other drivers. Certain drivers (such as PCI Express Root Port #3 - 9C14) when updating would also reinstall the Unknown USB Device, which I would then uninstall and keep working down the list. At the end of updating EVERYTHING I scanned for hardware changes
and "found" the Unknown USB Device.
From what I can tell, and I know very little about this stuff, my computer can't name one of my USB ports. Since it can't figure out what it's called it can't download the proper driver for it. Since it can't download the proper driver it can't work properly.
The practical result from this is that one of my three USB ports does nothing when I put in any USB item (connect my android phone, thumb drive, presentation clicker, etc).
I've looked on tons of forums. My current thought is that if I can tell my computer what the deice is or download the right driver and tell my computer to use that driver for this device it should solve my issue. But I don't know how to know what the name
of the USB port should be (I imagine it woul... Read more

Few days ago suddenly my Logitech MX master mouse (bluetooth connected) stopped working. Then I figured that Bluetooth can not be enabled. Then I saw that in Device manager have problem with unknown usb device, which device decriptor failed. Usb ports are without any device connected. All four of them empty now. Any kind of windows, usb/bluetooth driver update/uninstallation is not helping, so this is why I am trying to find help. So please help.

I was just working happily when my Microsoft Bluetooth Mouse just suddenly stopped working.The Bluetooth settings page says "Bluetooth is turned off" and there are no options on the settings page or the system tray to turn Bluetooth on.The Device Manager now has "Unknown USB device - device descriptor request failed" where it did not before.Other devices all seem to be working fine - USB devices plugged in are being recognized and work properly. Only BT seems to be broken.I've tried:uninstalling the device and rebootinginstalling the latest updated chipset drivers from the dell websitewindows updatespretty much all of the advice here: http ://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed

So in desperation I just went into BIOS settings to see if there are any BT settings that may have become disabled. I didn't see any, and I didn't change any other settings.After rebooting, BT and my mouse is now working again.Something seems to be really flaky here, but hopefully this will help others with the same issue.

Hey1.)So my mouse(Corsair Harpoon RGB) was recently just working fine until one night i unplugged it and put it into computer and on that computer it didnt work so i went back to my laptop to plug it in there, but it showed the same problem it didnt respond the logo didn't light up so i went to the device manager and it said *title. So how do i fix this is there something with my mouse is there something with my software?Oh yea and on top of that i have 2 more issues that i jut can't solve by myself.

2.) Unknown USB-device(port reset failed)3.)DVD Drive(optical drive) doesnt show up on the device manager but it sounds like it's working and it opens and closes.4.)Front ports of my PC doesnt work if i plug an USB in it doesnt do anything (it does work perfectly in the back)

I don't know though if i should make more threads but they somewhat relate to each other,that's why they are just in 1 thread. If you need to ask any question, need pictures , my specifications or anything else just ask me.Thanks in advance!Best regards Hao.

Im running windows 10 on an HP laptop, 64 bit, and i just got a micro usb to usb device so i can transfer stuff onto my phone. It worked when i first got it but now it comes up with a Device Descriptor Request Failed and a Code 43 error. Ive tried updating
the drivers, restarting my laptop, and plugging it into different usb ports but it still comes up with the error. Any suggestions?

I have had the Microsoft Wireless 2000 Keyboard and mouse for 10 months and it has been working fine. But recently when I plugged it in I got an error message which said :The last USB Device you connected to this computer malfunctioned. and Windows does
not recognize it.
I opened Devices and Printers and it said Unknown USB Device (Device Descriptor Request Failed).

Hi, i am having weird problem on windows 10. i fresh installed today and was installing drivers and other softwares. i couldnt set fingerprint because it says biometric device is not enabled. then i realized this error code : 43 . i dont know if it s related with fingerprint or not. also i installed old driver of integrated webcam in compatible mode win 7. i dont know if it caused this problem either. any help please?

Done!it was Fingerprint. fingerprint socket was unplugged. after i re-plugged the socket windows recognized biometric device. then i installed thinkpad fingerprint driver 6.0, all worked fine. there is no unknown usb device anymore. regards,

After installing Windows 10 anniversary update, I get the following error in the device manger: Unknown USB Device (Device Descriptor Request Failed)

Tried uninstalling and restarting PC. Reinstalled Windows made from media tool. Nothing fixed it. Did a google search and nothing has worked. No USB drivers on the PC maker's website.

Any ideas?

You can try going into device manager > select show hidden devices and delete all "inactive" usb device appearances. In my example below, there would be four. Once done, reboot and try your device again:

Hello,I have been facing a problem with my USB devices for the past few weeks. Whenever I connect a USB device (mouse, iPhone or even a USB), I get the error Unknown USB Device (Device Descriptor Request Failed) Windows has stopped this device because it has reported problems. (Code 43). As a result, i am unable to connect any USB device to my computer which is very frustrating. In addition to that, I have also discovered that my Bluetooth Devices also shows a similar message Unknown USB Device (Device Descriptor Request Failed) Driver Error. I tried to connect devices (phone, a wireless headset) to my computer but that also failed. I have tried various solutions from the internet (disabling/uninstalling USB devices, reinstalling Bluetooth drivers, etc) but none of these seem to fix the problem. I do not know what the root cause of this problem and i would be very happy if you could guide me on this problem. Following are the details about my laptop and windows along with a screenshot of the errors: Laptop - Lenovo G50-70, Core i5, 8 GB RAMWindows 10 - Version 1809 (OS Build 17763.253) Would appreciate any help that you could provide.Regards,Usman

Can any help with this problem? Have a Pavilion G6 with no USB 3.0 as I am aware. USB (3 ports) not working.However, when the plugged the mobile, the mobile does get charged. Device Manager shows "Unknown USB Device (Device Descriptor Request Failed)". Running Windows 10 64 bit. Tried everything like uninstalling, updating etc as the information on the internet. Also, updated the drivers using Driver Easy but still getting the error. Any suggests, please? Thanks in advance. Sanil Sukumaran.

I'm pretty sure everything is working as should, you're good minus the minor annoyance if all device connected through the USB Hub is recognized by Windows; if you right click Properties on the yellow triangle it probably says "The Device is working properly".

I know that a similar question has been asked before but, not with the last part of the message, (Device Descriptor Request Failed). I get this, in Device Manager, and I have searched for an answer on the net. Also it is a Code 43. I went through my laptop, with an HP Technician this morning, I might add at a cost of 5p/minute, for 30 odd minutes. He has said that because I had gone over to Windows 8.1 and the recovery discs I made will not load, to put back in Windows 8. I have to send the laptop back for re-installing the OS, because Windows 8.1 do not have the update for my problem. Also the R.H. USB socket has a failure ID:0GAPTK-6T7716-MFPWWK-8D1Q03. I personally think that this is all what the problem is. a duff USB. Is this a cop-out???My question is; has anyone heard of Windows 8.1 having driver WHQL problems?? Very.

Any/all ideas, appreciated.

ps, I only found out the problem with the usb when I tried to download a Mobi file to a Kindle for my wife. The other usb's work OK.

A:Unknown USB Device (Device Descriptor Request Failed)

Is there only one USB port on the right hand side? Sometimes manufacturers connect internal devices via an unused USB port internally. USB ports are usually in groups of two, seeing only one port is usually a sign that the wiring has been redirected internally to something else like a Bluetooth adapter or wifi adapter. It may even be a card reader or touchpad. Is anything like that not working? If it is start looking for a driver for it.

My computer keeps telling me Unknown USB Device (Device Descriptor Request Failed), so I looked up how to fix it and they told me to uninstall it then scan for hardware changes and it will reappear working properly. Only it did not come back working properly, it came back the same. I am also 98% sure that this "unknown USB device" is my built-in webcam that has never once worked. So if someone wants to help me out and allow me to use my webcam that would be great!

A:Unknown USB Device (Device Descriptor Request Failed)

Hi there, can you first tell us what is the Name and Model number of your system?

What OS are you running

im sorry if you already listed this, as I cannot see your specs from the Windows Forum App..

Hello, I seem to be having an issue with my Thinkpad T470p. I've had it for about a year and a few months ago, all the 3 USB ports stopped working and so did the integrated camera. It would work at times and then stop working. For the past 2 weeks, everything has completely failed. So far I've done the following: -I've reset the BIOS to default settings and still there is no change.-The USB ports are enabled in BIOS settings as well. -Fast startup is diabled-The autosuspend for USB devices has been disabled in the power settings as well-All drivers have been updated using the Lenovo System Updates-This is a fresh install of Windows 10 so there is no previous state that I can go back to. (It wasn't working when I was running Ubuntu either even with all the right drivers installed.)-Troubleshooting cannot seem to find a fix for the error either One weird thing though is that my WD Elemnts HDD works fine when plugged in to any of the USB ports but other than that nothing else works. Any and all help will be much appreciated. My warranty expired just before these issues started so I don't really think I can get it repaired by Lenovo services.

I have a problem that bugs me for years, I never intentionally solved it, sometimes those errors disappears and all USB ports work fine, sometimes they do not. So anyone can help me please, it would be great.

Some of my ports do not work all the time, I cannot identify a specific moment. Inside the Device Manager, Universal Serial Bus controllers, I get 1, 2 or more "Unknown USB Device ( Device Descriptior Request Failed )", sometimes more sometimes less.

CPU: Intel Core i7 3770Motherboard: AsROCK H77 Pro4/MVPWindows 10 all available updates downloaded and installed as of today, and everyday. The problem appeared on Win 8 or 7, not sure when. So it's not necessarily Windows 10 specific. I ported it to 10. Here is what they look like:http://prntscr.com/d6rm6k

Bios is up to date. Chipset drivers updated, various solution tried from googling, I even managed to make all USB ports stop working testing some of these solutions, I had to restore windows from a ghost image I had.

It's like these USB ports remain suspended sometimes.

Any advice on what to try? The most annoying part is that from the frontal USB ports some stop working randomly too.

I'm experiencing slim keyboard not being recognized in the Windows 8.1The keyboard was working fine until just one day it just stopped working.I tried factory reset literally 8 times along with most recent BIOS update and dell's recommended update software. + power setting --> disabling power saving on USBIt still come up as unrecognized each time even with fresh reinstall.I was wondering if this is a hardware issue or just software bug from factory reset.I don't think there is a available driver for this kind of problem is there?

hey, im having problems with plugging in my mouse to any USB port, this just started around an hour ago. ive checked on the brand's website which carried no complaints on problems like this with the same mouse. tried pretty much everything, even looking
it up on youtube and forums... Nothing has worked, worser still, i got it for christmas and its stopped working, ive looked though the device manager too. Please try and help me, if u can. I use Razer Naga Waith Red if that helps

thanks,

A:Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor failed.

Hi onyx,
This error means a device driver notified the operating system that the device failed. This circumstance can occur if the device hardware fails or if the device driver fails.
Have you tried to update the device driver for test?
Please follow this guide trying t resolve this issue:

Hello, ok so after recently doing a clean install of windows 10(please don't get me started on that mess). my system has been plagued by random usb drops. it's where everything connected via USB suddenly disconnects then reconnects out of the blue. well I was using a Rosewill Transenclosure RX200R-APU-25B USB 3.0 dual 2.5 hard drive enclosure and transferring files from one drive to another (connected via USB) when one of these drops occurred. Now whenever I plug in my hard drive enclosure in a windows warning pops up and says "the USB drive that was just connected Malfunctioned and could not be installed" and in system manager it says "Unknown USB device (device descriptor request failed)". I know it's not the hard drives because I can remove them and use another connection and they work fine, all files intact. It's just now my hard drive enclosure won't recognize. This also happened to a "Loot crate exclusive Game of Thrones stark sigil 4GB USB stick I plugged in and turned into a windows 10 install drive. When I plugged it into use it after the windows media creator said it was done the USB stick was raw and unformatable. Please help. Microsoft keeps telling me it's a hardware issue even though it happened on two different systems. both operating windows 10 never any issue with windows 7 or 8.1

I have an external Bluray/DVD drive (ODP1201=S3-B) that works perfectly on Windows 7 but is not recognised by my new laptop which has Windows 8.1 64 bit. Can anybody explain why this is and what I do to get pass it, or is this a problem with Windows 8.1?

The device is listed in Win 7 as "hp bd rom bc 5501h", and the driver is 6.1.7601.17514

I have now tried various USB devices; I have connected a USB 2.0 External Hard Drive and a USB 2.0 Canon Camera both of which work OK, I have also connected a Seagate 1T external drive which is USB 3.0 an that was OK as well (the ports are all USB 3.0 on the laptop hence the reference to the which USB type)

I have been advised that this error can arise when a drive doesn't receive enough power from the system. The device does have two USB connectors, I have tried using both of them. The power cable going to the powered USB on the laptop and the data going to the adjacent USB (there are a pair of USB sockets on either side of the laptop, the right hand side having the only powered socket).

A:Unknown USB Device - A request for the USB device descript

I'm too of opinion that it's a power issue. Laptops are not known to have much power thru USB ports, not even some desktops for that matter. Possible solutions: If that laptop has USB3 port you can try it in there, it gives more power and is compatible with USB2. Another one is to ad external power to the drive. One of the USB connectors on the twin cable has only two connection tabs and is for extra power to device. That one can be connected to universal USB charger for phones etc. That's how I solved a problem with a HDD in external enclosure.

i have acer e1-571 notebook.running windows 10.from last few days my pc giving this error-Currently, this hardware device is not connected to the computer. (Code 45)

To fix this problem, reconnect this hardware device to the computer.

i have tried all kind of suggestions
given by microsoft related this problem .but cant solved.card reader ,pen drive ,external keyboard ,or external mouse no one working.2.some random keys is not working .please fix my issue .

hello guys in my device manager there is a yellow triangle on a usb device driver saying : a request for device descriptor request failed first i thought maybe 1 of my us ports not working but when i tested all ports are working even card reader but the error is still there i updated drivers (chipset - etc) but it didnt help so i want to know how to get rid of that error and what is the problem with my laptop?note: sometimes when i trun on my laptop that error is gone mysteriously and most of the times its showing up note: i recently changed my wireless adapter tho the orginial adapter was a bt/wifi combo but the new one is just a wifi adapter and i have an ssd installed instead of dvd optical drive and both are working wellnote: things i already tried: disabling fast boot-updating generic usb drivers-taking out battery for 5 minutes-updating drivers

Let me start out by saying that I've googled the shit out of this problem, tried several things, and nothing worked.

I have a D-Link USB 2.0 Hub that I got about a week ago. It's been working awesome up until recently. It's a plug and play device, however windows is failing to recognize it, and thus making everything I have plugged into it unusable.

In the 'Device Status' box it says:

Code:
Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.

And in the 'Events' tab, there's a few listed, I'm not sure if they are much help:

having trouble installing an Epson WF-2530 printer onto win 8.1 machines. i have 3 win 8.1/64 bit machines. it will install and is working on only one. used the same installation disc, and install process, and cables with all 3 machines. googling the problem shows plenty of stuff mainly updating drivers. done that, still no good.Not sure why it works on only one, a generic clevo laptop w550eu.thoughts??? the installation process stumbles when it asks you to connect the printer cable to the computer.

I do not over clock. I have the ram overclocked in the BIOS using XMP to 3000 speed, but that's it.

Here is my situation, and I am baffled and feel super deflated over this mess as I run a small project studio for video and audio work and this is causing me to fall behind on projects.

I am getting constant on screen pop up notifications that a recent USB device isn't recognizable or 'has malfunctioned and windows doesn't recognize it' along with constant USB connect/disconnect sounds. I just built this custom PC this past week and everything seemed fine for a couple days, and then this started.

When it does this, I go into device manager, and I get a yellow exclamation mark under the USB list that says 'Unknown USB Device (Device Descriptor Request Failed). I have hit google search and tried every single suggestion I could find including the following:

-Blowing all the dust out of all the ports, although i doubt that was an issue because the case and motherboard are brand new.

-Going into device manager, and disabling or uninstalling the device that is giving the error. It pops right back ... Read more

Massive problem I have encountered since buying a new laptop pre-installed with Windows 8.1

I have 3 external USB storage devices - 1x Corsair "Slider" 64GB, 1x HiTachi Touro 750GB, & 1x HiTachi 4TB external drive. ALL drives are coming up with the same error message and are not being recognized by Windows 8.1

The strange thing is, I also have another 2 PCs - one with Win7 and one with WinXP and the drives work without issue.

I've spent the last 4 days scouring the net looking for answers, and thus I am here hoping someone can shed some light as to why ALL of these drives do not work on this new laptop pre-installed with Windows 8.1?

Even stranger still is I have other thumb drives, a cheap Transcend 32GB (which is USB3.0) and a few cheapo (USB2.0) drives of various sizes by Strontium, Lexar and so on which work perfectly.

But the one that has me o.O is an expensive 64GB thumb drive called the Mach Extreme which also works perfectly with this laptop???

So all up 2x HiTachi drives & 1x Corsair thumb drive are not working and its driving me bonkers!

If no drives worked at all, then I would be seeking the manufacturer for maybe a faulty component. Dodgy USB ports, or maybe a motherboard problem. But having a handfull of drives, of various makes, sizes and both USB3.0 - 2.0 fully working leaves me scratching the old chrome dome as to what could be the issue

I've always updated drivers, WinXP, Win7 and so on, the same way - download the driver, go into device manager and select browse, then point windows to the downloaded driver to update the necessary files. Its always worked that way for me for as long as I can remember.

Not so it appears with windows 8 - for some strang reason.

For me I had to update to the latest Intel Chipset Drivers, but instead of the tried and trusted methos above, you simply hit the setup.exe and let windows 8 do its thing. Believe it or not, but this fixed the issue.

Yes I had already updatd to the latest Intel Chipset Drivers using the device manager method, and yes windows "did" update ...someting??? But the USB devices were still showing the Unknown USB Device error. But using the setup.exe fixed the everything and all my USB devices are now working perfectly with Windows 8.

How, why, who knows, but I hope this works for others with the same problem.

I have a flash drive that I previously used in public computer lab (where many viruses linger) the other day to do my work. As I got home, the flash drive isn't working anymore, saying "USB Device not Recognized". I also noticed that it really took me a while to finally, safely remove it from the computer lab's PC. So I actually wonder if it actually removed my flash drive properly.

On Device Manager, it says "Unknown USB Device (Device Descriptor Request Failed)".On the Properties, the device status says "Windows has stopped this device because it has reported problems. (Code 43) -- A request for the USB device descriptor failed."

Things I have tried:- Shut down my PC, unplugged power and removed battery, waited for a while, booted my PC and try plugging in again.- On Device Manager, uninstalled it and scanned for hardware changes, it still returns as "Unknown USB Device".- On Device Manager, I clicked "Update Driver Software..." and it returns me a message saying "The best driver software for your device is already installed".- Unfortunately, when I visited Kingston's website to check if there is driver for this specific flash drive, there isn't any... "There are no downloads or drivers available for this product".- Used Windows 8's Troubleshooting tool. It only detected my problem, but was un... Read more

A:USB not recognized (Device Descriptor Request Failed)

if you have tried on other systems using different OS then the error is normally because of issues with the item not the PC , it might be 'confused' or have corrupted data or be faulty.

If you have the data still stored elsewhere...then you may be able to reset the flash drive and see if it recognises it then.

Was trying to plug my Toshiba 1tb External hard drive in to retrieve music off it and it wont recognize the drive. Device manager revealed the yellow triangle and error message. It works on my wifes hp streambook and also my kids stream book both are running wondows 10 like mine. I have tried nearly 10 different suggestions from google searches and have gotten nowhere. The only thing I couldnt try was turning off the usb in the power options, for some reason mine doesnt display that option. My notebook only has 1 usb port so I cant try a different port. Any suggestions or fixes?

Hello, The left USB socket on my X250 has started to return the message Device Descriptor Request Failed, but the right hand USB works as normal. I rarely used the left hand one so I am unsure for how long this has been the case, but now I am very keen to start using a USB keyboard so I am very keen to get it working again.I have tried uninstalling the device and reinstalling, and searching for new drivers.Thanks in advance for any help,Dave

I have a Kingston HyperX 64Gb memory stick, formatted FAT32, that Win8.1 doesn't recognize. I plug in the memory stick to any USB 3 or 2 port on a Dell XPS15-9530 and Win8.1 appears to recognize it, assigns a drive letter then immediately says "unknown
USB device (set address failed)". The memory stick works OK in two other Win7 machines. Interestingly, yesterday, Win8.1 was saying that the USB device was unknown because Device Descriptor Request Failed but that has now changed to Set Address Failed.
BIOS is up to date. All updates to Win8.1 have been applied. Kingston have no drivers for this device. I've tried setting USB power setting "Selective Suspend Setting, both battery and plugged in, to disabled and it makes no difference. I've removed
the device in "devices and printers" and then rescanned in device manager with no success. Is there anything further I can do?

windows 10 user , my usb ports are working fine but when i insert a usb , it doesnt read , when i go to my device manager it says that it has stopped because of code 43 , i tried installing and re installin , enabling and disabling but nothing is changing , please help? i dont know what to do anymore

Now when i completed the installation, i connected it and i had this error:Windows has stopped this device because it has reported problems. (Code 43)A request for the USB device descriptor failed.I used slimdrivers to update all the other drivers, in case it was a conflict causing the error.I checked via command prompt with command "pnputil -e" and i saw a driver from the vendor of the device listed, so it is installed correctly i think.I tried all USB ports i have, 3.0 and 2.0 on one side of laptop and 2.0 on other side.

When on device manager, if i click update drivers and choose the "let me pick from a list of device drivers.." i don't see the company name of the device.

i saw that another guy posted a really similar problem on SevenForum and he figured out how to force windows to use the drivers but he didn't post the solution.. Here is the post: Can't get Windows 7 x64 to use the drivers I've installed repeatedly Solved - Windows 7 Help Forums

A:USB device not recognized. Device descriptor request faile

I am having the same exact problem as you, Cattanius. I couldn't get it to connect to my computer over 2 years ago and then just decided to try it the other day. I didn't expect anything to show up in device manager because I thought the usb port was fubar, but then I see the same message you got and all of the sudden there's hope! I hope.

hello all. i dont come around to this site very often but i desperately need you guys help.

im trying to get a gamebridge i purchased a few days ago to work. the first day i had everything going according to plan and had it installed on there and everything, but then i was having problems with it... it wouldnt show my game screen. so i decided to install to a new usb drive.

i took the device out and tried to reinstall to another drive but it didnt work... and now when i try to put it back into the original drive it gave me an error. so i went into device manager and unistall the device manually from the original drive.

but now i try to install it again to any drive it give me the code 28 error...someone please help me i really need to fix this problem.

hie i have just installed window 7 and this devices are missing, any help will be very much appreciated.base system devicedevice idPCI\VEN_1217&DEV_7110&SUBSYS_117C10&PEV_00PCI\VEN_1217&DEV_7110&SUBSYS_117C10CFPCI\VEN_1217&DEV_7110&CC_088000PCI\VEN_1217&DEV_7110&CC_0880

Note: Device manager lists appropriate bluetooth antennae. Some items are still showing up ok, but many (some new, some previously paired) are listed as unknown now, so they are useless to me until this is resolved. This is a fairly new Flex5 (bought at Microcenter about a month ago).I ran the Lenovo "Vantage" program to get the latest bluetooth drivers on board.Tried uninstalling BT driver and running manual install of intel and Qualcomm drivers. Windows10 is not seeing the Intel ones, I think as when I try to change the driver to the intel ones I only see the the QualcommAtheros and the generic bluetooth drivers available. I ran that installation a number of times, but havn't been able to try the Intel drivers yet. I'm not sure if they will fix the problem, but would like to try them, unless someone here can point me at something else that may be the cause. Thanks for any info!

I just bought myself a Powercolor Radeon HD 4890 yesterday. After installing the card and the required drivers everything works like a charm. However, every time I start up my PC I get a message saying that a new device has been found on my system. On checking Device Manager I found an "Unknown device" entry under "Other devices".

I'm attaching a screenshot of Device Manager.

Are there any drivers I'm missing? It only happened after removing my old card (after uninstalling all its drivers) and installing the Radeon.

Any help is greatly appreciated.

Thanks.

A:Unknown Device In Device Manager After Installing Radeon HD 4890

I have a Powercolor Radeon HD 4890 (I also have a Gigabyte 4890 and XFX 4890 in two other PCs). I think you need to install the latest ATI Catalyst Suite. You may have installed the driver only package. Anyway, I think it has to do with the HDMI capabilities of the card. High def sound is built into the card (the HD part of the card name) and the HD sound driver is part of the Catalyst Suite. When you use an HDMI cable to an appropriate display, HD sound is also transmitted through the same cable from the Radeon graphics card.

Of course, be sure to install .NET Framework 2.0 as it is required before you can install the full Catalyst Suite. The HD sound driver won't install without it. At least I had trouble before I installed .NET 3.5. I went to Windows Update and installed .NET Framework 3.5. 2.0 is included in that update and 2.0 wasn't available separately.

How do i figure out what driver or even component windows wants software for when in the device manager under other devices it lists an unknown device and windows update cannot find anything.

Oh and is it appropriate for me to use this topic to ask another question regarding explorer.exe as while i am inside a folder i delete (by choosing delete from the context menu in the tree view) while inside that folder on this particular laptop PC explorer. always crashes, collect information, sends it and restarts explorer. I have not experienced this problem on any other pc running any version of windows 7, oh and the same happened with build 7264 x32 and the current install of build 7600 x64.
